How high should vacuum breakers for hose connections in healthcare laboratory areas be above the floor?

  1. 4 feet

  2. 5 feet

  3. 6 feet

  4. 7 feet

The correct answer is: 6 feet

Vacuum breakers for hose connections in healthcare laboratory areas must be installed at a height of 6 feet above the floor to ensure proper protection against backflow and to comply with health and safety regulations. The elevation prevents any potential contamination that might arise from spills or splashes occurring at lower heights, which could compromise the cleanliness and sterility of laboratory environments. This height requirement is particularly critical in healthcare and laboratory settings, where maintaining strict hygiene standards is essential. By positioning vacuum breakers at this specific height, it mitigates the risk of water being siphoned back into the potable water supply, thus promoting safe and sanitary practices in these sensitive areas.
